Arnold Kling explains the Corruption Trap:
The World Bank’s Philip Keefer says that young democracies are fragile because governments are weak. Weak governments, unable to sustain broad-based power, turn to corruption in order to retain narrow-based power. However, corruption discredits the government, making broad-based power even less available. This makes the government even more dependent on corruption for survival. I call this the Corruption Trap.
